Description
[0001] The invention relates to a coil transport pallet for
transporting a wound coil, with a support device for temporarily
supporting the wound coil, with a coupling unit for coupling to a
coil transport vehicle and/or with rolling and/or sliding surfaces
for interaction with a ground conveyor device.
[0002] The invention further relates to a coil transport vehicle,
in particular a coil discharge carriage, with a pallet
accommodation for accommodating a coil transport pallet.
[0003] The invention furthermore relates to a method for
discharging a coil wound on a winding system, in particular a coil
wound from a steel strip, in which at least one winding layer
and/or winding layer end of the wound coil is/are pressed by means
of a pressing mechanism against the wound coil, in which the wound
coil is deposited on a coil transport vehicle, in particular on a
coil discharge carriage, in order to discharge this wound coil from
the winding system and provide it for further processing.
[0004] In the prior art, there are many coil discharge and coil
transport options by means of which a coil wound on a winding
system can be discharged from this winding system and transported
for further processing directly to a corresponding further
processing system or to a temporary storage where the wound coil
can be stored temporarily.
[0005] In particular in the case of wound coils made of a material
strip of greater strength such as a steel strip, for example, there
is an increased risk that the wound coil "springs open"
accidentally; that is to say that at least the outer curved winding
layers of the coil unbend again partially, resulting at least in
making the further processing of this wound coil considerably more
difficult. In order to prevent such a springing open of the wound
coil, the wound coil is firmly tied immediately after the winding
with the aid of a tying machine. This tying by means of appropriate
tying elements is not only costly and time consuming, but it also
entails additionally the disadvantage that the wound coil can be
damaged on its outer side. In addition, in the handling of the
wound coil, associated tying elements of a corresponding tying can
be damaged, resulting in the risk that the wound coil could
unexpectedly spring open during coil transport and, in the process,
it could even injure personnel in the worst case.
[0006] Furthermore, during coil transport between the winding
system and the further processing system or the temporary storage,
the wound coil is commonly often transferred multiple times. More
precisely, during coil transport, the wound coil is at various
times picked up, deposited, transported further, picked up again,
etc. However, due to this handling, there is also an increase in
the risk that the wound coil is damaged, for example, by a
discharge device provided on the winding system, by means of which
the wound coil is discharged from the winding system and/or already
due to a multitude of deposition marks, which can easily be
produced on the outer winding layer of the coil, in particular when
it is deposited repeatedly at different times onto different
supports. This disadvantage is already remedied by transporting the
coil on a coil transport pallet as coil/pallet unit.
[0007] In addition, it is a considerable disadvantage if the
windings are shifted among themselves due to frequent lifting and
lowering of the wound coil during coil transport and the individual
winding layers loosen as a result. This has an extremely
disadvantageous effect on the shape stability of the wound coil,
further increasing the risk of mechanical damage to the wound coil.
This disadvantage too can be counteracted by coil transport by
means of a coil transport pallet.
[0008] In particular, the underlying aim of the invention is to
further develop the discharge process at the end of a coil winding
process on a winding system, so that the above-mentioned
disadvantages in particular can be overcome.
[0009] The aim of the invention is achieved by a coil transport
pallet for transporting a wound coil, with a support device for
temporarily supporting the wound coil, with a coupling unit for
coupling to a coil transport vehicle and/or with rolling and/or
sliding surfaces for interaction with a ground conveyor device,
wherein the coil transport pallet has a through-opening for guiding
a pressing element of a pressing mechanism therethrough, for
pressing at least one winding layer and/or winding layer end
against the wound coil.
[0010] By means of this through-opening provided on the coil
transport pallet, a pressing mechanism can interact in a manner not
known to date with the wound coil which is held by the winding
mandrel, so that the entire discharge process for discharging the
finished wound coil from the winding system can be designed more
simply.
[0011] In particular, a coil/pallet unit can be produced
advantageously by means of the present coil transport pallet.
[0012] The term "coil/pallet unit" in the sense of the invention
describes a unit which consists substantially of the above coil
transport pallet and of a wound coil associated with said coil
transport pallet on a winding system for coil transport, wherein
the coil is deposited temporarily on the coil transport pallet in
an operationally reliable manner.
[0013] In particular, the present novel coil transport pallet
allows another placement possibility of the pressing mechanism and
thus also a new design of a device for discharging a coil wound on
a winding system, as explained in further detail below.
[0014] In any case, the coil transport pallet has a pressing
element through-opening, so that at least the outer winding layer
and/or the outer winding layer end of the wound coil can be pressed
by means of a pressing element through the coil transport pallet
against the wound coil.
[0015] This is already achieved while the wound coil in the winding
system and, with the removal from the winding mandrel of the
winding system, is deposited on the coil transport pallet.
[0016] Thus, the coil transport pallet in the sense of the
invention forms a pressing element through-opening which is
specifically adjusted to the size of the pressing element in such a
manner that said pressing element can be passed through the coil
transport pallet to the wound coil.
[0017] In the sense of the invention, the present coil transport
pallet is preferably a coil transport pallet which can be
associated, in particular, with a coil transport vehicle
implemented as coil discharge carriage.
[0018] It should be understood that the present through-opening can
have a wide variety of designs in order to allow, in particular, an
interaction of the pressing element of the pressing mechanism
arranged on the coil transport vehicle with the coil.
[0019] The through-opening can be implemented in a manner which is
particularly advantageous and easily accessible from a structural
standpoint if it is surrounded at least partially, preferably
completely, by the construction of the support device.
[0020] In particular, if the construction of the support device
completely surrounds the through-opening, the through-opening can
be enclosed by the support device in the form of a closed ring, so
that the construction of the support device is particularly
stable.
[0021] To that extent, it is advantageous if the construction of
the support device surrounds the through-opening is at least
partially.
[0022] The support device of the coil transport pallet is here
designed in such a manner that the wound coil coming from the
winding mandrel can be deposited reliably. To that extent, the
support device is used for removing and supporting the wound coil
on the coil transport pallet.
[0023] The coupling surfaces of the coupling unit provided on the
coil transport pallet are preferably arranged on the lower side of
the coil transport pallet or so that they are accessible from the
lower side and they are part of the coupling unit, by means of
which the coil transport pallet can be temporarily coupled in an
operationally reliable manner to the coil transport vehicle.
[0024] The rolling and/or sliding surfaces are also preferably
arranged on the lower side of the coil transport pallet. These
rolling and/or sliding surfaces can interact with a correspondingly
complementary formed forced guidance device, for example, the
stationary ground conveyor device, if the coil transport pallet is
to be transported on the present ground conveyor device.
[0025] Preferably, the coil transport pallet has a rollerless
design, so that the rolling and/or sliding surfaces are
implemented, for example, by runners or the like, which can move
satisfactorily along a roller table lane of the stationary ground
conveyor device.
[0026] In the present case, the coil transport vehicle is designed
to be mobile and the ground conveyor device is designed to be
stationary.
[0027] The present through-opening can be placed on the coil
transport pallet advantageously with regard to the pressing
mechanism, if the through-opening is arranged between two coupling
spaces spaced from one another by the through-opening and/or
between two runners spaced from one another by the through-opening
and forming the rolling and/or sliding surfaces. As a result, the
pressing element can advantageously interact with the wound coil in
order to produce a coil/pallet unit in an uncomplicated and
operationally reliable manner.
[0028] The construction of the coil transport pallet can be further
simplified from a structural standpoint if the through-opening is
arranged beneath the support device. As a result, in particular,
the pressing element of the pressing mechanism can be guided
satisfactorily from below against the wound coil, when the coil
transport pallet is on the coil transport vehicle.
[0029] In particular, it is advantageous if the through-opening is
arranged on a side of the coil transport pallet facing the coil
transport vehicle.
[0030] The coil/pallet unit can be produced particularly simply, if
the through-opening is arranged in a trough of the support device.
As a result, the pressing element can be led from beneath the
trough to the wound coil.
[0031] The trough here forms a depression on the support device or
on the coil transport pallet, so that the wound coil can be placed
particularly deep in (the coil transport pallet and thus can also
be arranged as close as possible to the coil transport vehicle.
[0032] Therefore, it is advantageous if the pressing element or the
pressing roller is designed as a trough roller element which is
arranged in the trough.
[0033] Finally, to that extent it is advantageous if the
through-opening is arranged on the lower side of the coil transport
pallet, since, as a result, the pressing mechanism can be guided in
a conceptually simple manner to the wound coil.
[0034] In other words, arranged on the lower side means that the
through-opening is arranged in a plane defined by the longitudinal
and transverse extent of the coil transport pallet, wherein this
through-opening perforates this plane in such a manner that the
coil transport pallet can be physically penetrated particularly
from below.
[0035] The through-opening thus opens the coil transport pallet
downward, and, in particular, in such a way that the coil transport
pallet can be penetrated at least partially from below by the
pressing mechanism.
[0036] Furthermore, it is advantageous if the through-opening has a
longitudinal orientation oriented in the direction of the
longitudinal extent of the coil transport pallet. As a result, the
through-opening can be oriented substantially axially parallel to
the longitudinal extent and in particular to the preferred
transport direction of the coil transport pallet.
[0037] If the through-opening has a longitudinal orientation
oriented in the direction of the longitudinal extent of a coil
accommodation space formed by the support device, the pressing
element can interact without problem with the coil preferably over
the entire coil width, as a result of which the coil/pallet unit
can be produced with qualitatively higher value.
[0038] In the same way, an advantageous effect on the production of
the coil/pallet unit can be obtained if the through-opening has a
longitudinal orientation oriented in the direction of the coil
rotation axis of a coil deposited on the support device.
[0039] A good interaction between the wound coil and the pressing
mechanism can moreover be promoted if the through-opening has a
longitudinal orientation oriented in the direction of the rotation
axis of the pressing element.
[0040] The structure of the coil discharge pallet can be designed
even more advantageously if the through-opening is arranged so that
it extends transversely to a coil tying direction provided on the
coil transport pallet and/or transverse to a coil tying opening
arranged on the coil transport pallet.
[0041] In particular, the coil transport pallet and especially the
support device can be designed with bar elements in such a manner
that the wound coil can be deposited on small-construction fork
elements, which provides a reduced deposition surface for the wound
coil. The gap between the bar elements and the fork elements can
here be used for arranging the through-opening for guiding through
of the pressing element of the pressing mechanism for pressing at
least one winding layer and/or winding layer end against the
coil.
[0042] The design of the proposed coil transport pallet ensures, in
particular, a particularly reliable coil accommodation and also
provides, if necessary or desirable, a good possibility of
additionally tying the wound coil on the coil transport pallet.
Moreover, there is also the possibility of further processing in a
coil inspection.
[0043] Furthermore, as described, the discharge process can be
significantly improved if the through-opening provided on the coil
transport pallet is arranged with respect to the coil transport
vehicle in such a manner that a pressing mechanism arranged on the
coil transport vehicle can be guided at least partially through
this through-opening, so that its pressing elements can interact
with the wound coil independently of the site at which the finished
wound coil is retained. It is not important here whether the wound
coil is located still inside or outside of the winding system.
[0044] To that extent, a preferred embodiment variant provides that
the pressing element can interact with the wound coil both inside
and outside of the winding system. More precisely, in the present
case, the pressing mechanism can interact with the wound coil if
the wound coil, on the one hand, is still held inside the winding
system on a winding mandrel and if the wound coil, on the other
hand, is deposited on the coil transport vehicle and possibly
transported out of the winding system by means of said coil
transport vehicle.
[0045] In this connection, the aim of the invention is also
achieved by a coil transport vehicle, in particular by a coil
discharge carriage, with a pallet accommodation for accommodating a
coil transport pallet, wherein the coil transport vehicle comprises
a pressing mechanism with a displaceable pressing element for
pressing at least one winding layer and/or winding layer end
against the wound coil, and wherein the displaceable pressing
element is mounted linearly displaceably with respect to the coil
transport vehicle on said coil transport vehicle.
[0046] By means of such a coil transport vehicle, the discharge
process can be implemented very simply in terms of construction
using the present coil transport pallet.
[0047] A preferred embodiment variant provides that the
displaceable pressing element is arranged on the coil transport
vehicle linearly displaceably in such a manner that it can be
displaced vertically through a through-opening formed on the coil
transport pallet. Thus, the displaceable pressing element can
advantageously be guided through the through-opening arranged
beneath the support device.
[0048] The term "vertical" in the present case describes a movement
of the displaceable pressing element, which has a component in
vertical direction.
[0049] Another advantageous embodiment variant provides that the
displaceable pressing element is arranged on the coil transport
vehicle linearly displaceably with respect to a pallet moving
device of the coil transport vehicle, wherein by means of the
pallet moving device a coil transport pallet received by the coil
transport vehicle can be moved on this coil transport vehicle. As a
result, the displaceable pressing element can be displaced or
placed independently of a relative movement between the coil
transport pallet and the coil transport vehicle with respect to the
wound coil, whereby the coil/pallet unit can be produced more
simply on the winding system.
[0050] The term "pallet moving device" here describes overall a
device on the coil transport vehicle with the help of which the
coil transport pallet can be moved vertically on the coil transport
vehicle. In other words, this coil transport pallet can be lifted
or lowered on the coil transport vehicle.
[0051] Preferably, the present pallet accommodation is a movable
component of the pallet moving device, so that the pallet
accommodation in the sense of the invention can be lifted or
lowered.
[0052] The production of the coil/pallet unit can be designed even
more advantageously if the displaceable pressing element and a
pallet moving device of the coil transport vehicle are arranged so
as to be linearly displaceable independently of one another with
respect to the coil transport vehicle and with respect to a coil
transport pallet accommodated by said coil transport vehicle. As a
result, the displaceable pressing element can already be brought in
operational contact with the wound coil when the coil transport
pallet is still held a distance from the wound coil.
[0053] In the case at hand, the displaceable pressing element can
be formed, for example, as driven or non-driven roller element or
the like. However, other design variants are also possible.
[0054] Preferably, the displaceable pressing element is also
adjustable horizontally for placement with different setting angles
relative to the rotation axis of the wound coil and/or vertically
for raising or lowering.
[0055] Preferably, the pressing mechanism or its displaceable
pressing element is arranged on the mobile coil transport vehicle
in such a manner that, in particular, the pressing element is
arranged on the mobile coil transport vehicle so that it is
displaceable relative to the coupling device formed at least
partially by the mobile coil transport vehicle.
[0056] In the sense of the invention the term "coupling device"
describes a device by means of which the coil transport pallet can
be fixed in a particularly operational reliable manner on the
pallet moving device, so that the coil transport pallet is very
well secured with respect to unintended release.
[0057] Preferably, the coupling device is formed in such a manner
that a centering of the coil transport pallet on the mobile coil
transport vehicle can occur immediately.
[0058] An advantageous positioning of the wound coil can be
achieved, for example, by different starting positions of the
mobile coil transport vehicle.
[0059] The present displaceable pressing element of the pressing
mechanism of the coil transport vehicle can interact from a
structural standpoint in a particularly simple way with the coil
wound on the winding system if the coil transport vehicle is
characterized by a coil transport pallet on which the invention is
based.
[0060] Moreover, the aim of the invention is also achieved by a
device for discharging a coil wound on a winding system, in
particular a coil wound from a steel strip, with a pressing
mechanism for pressing at least one winding layer and/or winding
layer end against the coil, wherein the pressing mechanism is
arranged on a coil transport vehicle, in particular on a coil
discharge carriage.
[0061] By means of the pressing mechanism arranged on the coil
transport vehicle, the latter can interact from a structural
standpoint in a particularly compact construction with the wound
coil.
[0062] The device can be formed particularly advantageously if it
includes a coil transport pallet according to one of the features
described here and/or a coil transport vehicle according to one of
the features described here.
[0063] The aim of the invention is also achieved by a method for
discharging a coil wound on a winding system, in particular a coil
wound from a steel strip, in which at least one winding layer
and/or winding layer end of the wound coil is/are pressed by means
of a pressing mechanism against the wound coil, in which the wound
coil is deposited on a coil transport vehicle, in particular on a
coil discharge carriage, in order to discharge this wound coil from
the winding system and provide it for a further processing, wherein
the method is characterized in that the pressing mechanism is
provided by means of the coil transport vehicle on the winding
system.
[0064] If the pressing mechanism is provided by the coil transport
vehicle on the winding system, it can interact advantageously with
a winding layer of the wound coil, which in turn is necessary for
an operationally reliable production of a coil/pallet unit.
[0065] Preferably, from the coil transport vehicle, a displaceable
pressing element of the pressing mechanism arranged on the coil
transport vehicle is pressed through a coil transport pallet
against the winding layer and/or winding layer end of the wound
coil.
[0066] Thereby, a very compactly operating pressing mechanism can
be implemented.
[0067] The displaceable pressing element can be pressed from a
structural standpoint simply against the wound coil if a
displaceable pressing element of the pressing mechanism arranged on
the coil transport vehicle is pressed vertically from below against
the winding layer and/or winding layer end of the wound coil.
[0068] The method can be varied particularly advantageously if a
displaceable pressing element of the pressing mechanism arranged on
the coil transport vehicle is pressed against the coil while the
coil is rotated by means of a winding mandrel of the winding
system. As a result, the winding layer end can be positioned very
advantageously with respect to the support device.
[0069] In general, the present invention can be explained again in
reference to a coil discharge and transport system of a coil wound
on a winding system, in particular a coil wound from a steel strip,
wherein the coil discharge and transport system is equipped with a
plurality of coil transport pallets for the temporary accommodation
of the wound coil, with at least one mobile coil transport vehicle
for discharging and optionally transporting the wound coil and/or
with a stationary ground conveyor device for transporting the wound
coil, in which the coil wound on the winding system is deposited
temporarily on the coil transport pallet, wherein the wound coil is
positioned on the coil transport pallet with the assistance of a
pressing mechanism for pressing at least one winding layer and/or
winding layer end against the coil, in order to produce a
coil/pallet unit in such a manner that the wound coil is prevented
from unwanted springing open of the winding layers when it is
deposited on the coil transport pallet.
[0070] In the sense of the invention, the term "coil discharge and
transport system" describes a system with a discharge device, by
means of which a strip wound on a winding system or the like can be
discharged as a wound coil from the winding system and preferably
transported further to temporary storage or to a downstream
processing system and transferred there. This discharge device
comprises at least the present coil transport pallet and the
present coil transport vehicle.
[0071] To that extent, the present coil discharge and transport
system or its discharge device for discharging the coil wound on
the winding system functions excellently in combination with the
present coil transport pallet and the present coil transport
vehicle.
[0072] In the present case, the term "winding system" describes a
system, by means of which a strip, in particular a steel strip, can
be wound to form a coil, so that this coil can be accommodated for
transport and/or temporary storage in an easier-to-manage and more
space saving manner. In the prior art, other terms such as coiler
etc. are also conventional alternatives to the expression "winding
system."
[0073] Due to the fact that at least the outer winding layer or the
outer strip end of the wound coil is pressed by the pressing
mechanism against the wound coil, the wound coil can be deposited
on the coil transport pallet in such a manner that the risk of
unwanted springing opening of the winding of the wound coil can
almost be excluded.
[0074] Advantageously, a use of a tying machine downstream of the
winding process directly after the winding system can be dispensed
with, whereby the transport of the coil wound on the winding system
is considerably simplified.
[0075] This means that the wound coil taken up by a winding mandrel
can subsequently be deposited directly onto the coil transport
pallet.
[0076] Thus, a coil/pallet unit can be produced directly on the
winding system and persist temporarily until the wound coil
deposited on the coil transport pallet with the assistance of the
pressing mechanism is in coil transport between the winding system
and another processing system or temporary storage.
[0077] As a result, the risk of the wound coil being mechanically
damaged during the tying by a tying machine is moreover
reduced.
[0078] The present invention can be used particularly
advantageously in connection with strip materials of high strength,
since, when wound to form a coil, these strip materials have a
tendency to spring open, so that, in this regard, special measures
have to be taken during the tying of wound coils, which is in turn
very expensive.
[0079] A preferred variant of the invention provides that a winding
layer end of the wound coil is positioned on the winding system
with respect to the pressing mechanism and/or the coil transport
pallet in such a manner that the winding layer end is pressed by
means of the pressing mechanism and/or coil transport pallet
against the wound coil.
[0080] Preferably, the winding layer end is turned in a range of a
17:00 o'clock position or a 19:00 o'clock position, for example, by
rotation of the winding mandrel, so that preferably first the
pressing mechanism and then the coil transport pallet can be
brought in operational contact with the winding layer end.
[0081] Furthermore, it is advantageous if just one coil transport
pallet is associated with the wound coil for coil transport between
the winding system and a further processing system and/or storage
device. As a result, the transport of the wound coil can be further
simplified significantly. Since the wound coil is received
satisfactorily reliably by the coil transport pallet, transfer
actions between two ground conveyor devices or the like can take
place in an uncomplicated and quicker manner
[0082] It should be understood that the coil transport of the wound
coil or the coil/pallet unit can be designed in a variety of
ways.
[0083] It is advantageous to design the coil transport so that the
coil/pallet unit produced on the winding system is transferred by
means of the mobile coil transport vehicle to the stationary ground
conveyor device, in order to transport just this coil/pallet unit
to a storage device and/or a further processing system.
[0084] It is particularly advantageous if the coil/pallet unit
produced on the winding system is first undone again for transfer
to a further processing installation and/or to a storage device, in
order to transfer the coil deposited temporarily on the coil
transport pallet to the further processing system and/or to the
storage device.
[0085] Preferably, the coil/pallet unit here persists
unchanged.
[0086] In other words, this means that once the wound coil has been
deposited on the coil transport pallet, it is not taken off the
coil transport pallet again and rearranged before the coil/pallet
unit has reached the further processing system or a temporary
storage.
[0087] The wound coil can very advantageously be moved by means of
the coil/pallet unit produced, if the coil/pallet unit produced on
the winding system is rotated during coil transport on the
stationary ground conveyor device at least once about a vertical
axis.
[0088] It is understood that the present pressing mechanism can
interact in quite diverse spatial positions and quite diverse ways
with the outer winding layer or with the strip end area of the
outer winding layer, in order to be able to deposit the wound coil
in a particularly tightly wound state on the coil transport
pallets.
[0089] The present coil transport vehicle can be designed
differently. Preferably, it is constructed as a coil discharge
carriage, by means of which the wound coil can be discharged from
the winding system and transferred to the stationary ground
conveyor device.
[0090] In this connection, it is advantageous if the mobile coil
transport vehicle comprises a railbound coil discharge carriage,
since thereby from a structural standpoint a particularly simple
and operationally reliable discharge of the wound coil on the
winding system can be ensured.
[0091] The invention can be used in a wide variety of systems such
as, for example, on a rolling mill for rolling strips, in
particular steel strips, with at least one winding system for
winding strips, which is downstream of at least one rolling device
of the rolling mill. As a result, the operation of the rolling mill
can be substantially improved overall.
[0092] Furthermore, in the process, the wound coil is then arranged
on the coil transport pallet in such a manner that a coil/pallet
unit is produced, which ideally does not have to be undone for
downstream coil transport to further processing or temporary
storage of the wound coil. To that extent, the discharge of the
wound coil can occur in such a manner that a repeated transfer of
the wound coil without coil transport pallet does not apply,
whereby the risk of damaging the coil can be nearly excluded. For
this purpose, the wound coil is preferably received, already in the
coil system, by a special coil transport pallet. Subsequently, the
wound coil is discharged or moved out of the winding system
together with the coil transport pallet as coil/pallet unit by
means of a coil discharge carriage and, for example, transported
further to another processing or treatment station. This is made
possible, on the one hand, by the special production of the present
coil/pallet unit with the assistance of a pressing mechanism and,
on the other hand, by the special design of the coil transport
pallet and also its interaction with the mobile coil transport
vehicle.
[0093] By means of the present invention, almost any strip
materials to be wound and any coil thicknesses and diameters can be
processed.
[0094] Additional features, effects and advantages of the present
invention are explained in reference to the appended drawing and
the description below in which, as an example, a first possible
coil transport pallet, a first possible coil transport vehicle and
to that extent also a first possible device for discharging a coil
wound on a winding system as well as, for example, an associated
coil discharge and transport system are represented and
described.

[0104] The coil delivery and transport system 1 shown in FIG. 1 as
an example and therefore also only partially comprises three
winding systems 2, 3, 4 which, at least in this embodiment example
shown, are downstream of a rolling mill, not further represented,
for rolling steel strips or the like.
[0105] However, these winding systems 2, 3 or 4 can also be
provided on other system areas or systems such as, in particular,
other forming systems or the like.
[0106] Each of the winding systems 2, 3 and 4 has a device 5 for
discharging a coil 6 wound on the winding system 2, 3 or 4, which
is shown and described in greater detail in FIGS. 5 to 8.
[0107] By means of the winding systems 2, 3 and 4, strips provided,
such as, in particular, steel strips 6A (see FIG. 5), are wound
compactly on their respective winding mandrels 7 (numbered only
exemplarily) to form the coil 6.
[0108] The coil discharge and transport system 1 moreover comprises
coil transport pallets 8 (see, in particular, FIG. 2) in order to
be able to deposit on each one of these coil transport pallets 8 in
each case a wound coil 6 in an operationally reliable manner so
that, on the respective winding system 2, 3 and 4, a coil/pallet
unit 10 can be produced at the same time.
[0109] The respective coil transport pallet 8 is provided by a
mobile coil transport vehicle 11 with a pallet accommodation 11A
(see, in particular, FIGS. 3 and 4) on each of the winding systems
2, 3 or 4.
[0110] The coil transport vehicle 11 is here designed as a
railbound coil discharge carriage 11 which can be moved along a
rail section 13, in order to produce a coil/pallet unit 10 from the
coil 6 wound on the winding system 2, 3 or 4 and the associated
provided coil transport pallet 8.
[0111] Subsequently, the latter is discharged by means of the coil
transport vehicle 11 from the winding system 2, 3 or 4 and
optionally transferred to a downstream stationary ground conveyor
device 15.
[0112] Furthermore, at least in this embodiment example, the coil
discharge and transport system 1 additionally also comprises the
stationarily installed ground conveyor device 15, by means of which
the respective coil/pallet unit 10 can be transported from the
winding system 2, 3 or 4 or from the corresponding coil discharge
carriage 11 to a further processing system (not shown) and/or a
storage device (not shown).
[0113] The stationarily installed ground conveyor device 15 is
characterized by roller table lane 16 (numbered only exemplarily)
inter alia as well as by rotating table units 17 (also numbered
only exemplarily), so that, in particular, the respective
coil/pallet unit 10 can be transported in different transport
directions.
[0114] For this purpose, the respective coil/pallet unit 10
produced on the winding system 2, 3 or 4 can be rotated during coil
transport around a vertical axis 18, so that the wound coil 6
deposited on the respective coil transport pallet 8 can always be
moved or transported as coil/pallet unit 10 within the coil
transport system 1 from the respective winding system 2, 3 or 4 to
the target site. In the process, this coil/pallet unit 10 is not
undone on the way, so that the wound coil 6 is always reliably
parked on the coil transport pallet 8.
[0115] The coil transport pallet 8 shown in further detail in FIG.
2 has, in the direction of its longitudinal axis 20, a longitudinal
extent 21 which is considerably longer than its transverse extent
22. In particular, the wound coil 6 lies on the coil transport
pallet 8 in such a manner that the coil rotation axis 23 (see FIGS.
5 to 8) of the wound coil 6 is oriented substantially in the same
way as the longitudinal axis 20.
[0116] In the design shown here as an example, the coil transport
pallet 8 has an outer runner frame 25 which, on the lower side 26,
of the coil transport pallet 8, forms a first runner 27 located on
the left next to the longitudinal axis 20 and an additional runner
28 located on the right next to the longitudinal axis 20.
[0117] To that extent, the coil transport pallet 8 is designed
without rollers.
[0118] The runners 27 and 28 form their own rolling and/or sliding
surfaces 29 (numbered only exemplarily), so that the coil transport
pallet 8 can be transported by means of these runners 27 and 28
excellently along the roller table lanes 16 of the stationary
ground conveyor device 15.
[0119] The coil transport pallet 8 moreover has an inner frame 30
which together with the outer runner frame 25 forms a framework 31
of the coil transport pallet 8.
[0120] By means of the inner frame 30, a support device 35 for
temporarily supporting the wound coil 6 is substantially
formed.
[0121] The support device 35 is designed in the shape of a trough,
so that in the trough 36 or depression (not numbered) thereof the
wound coil 6 can be reliably deposited.
[0122] Here, the support device 35 comprises at least two bar
elements 37 (numbered exemplarily), which substantially form the
trough 36. On these bar elements 37, the wound coil 6 can be
deposited.
[0123] A coil accommodation space 38, located particularly deep in
the coil transport pallet 8, can be formed on the coil transport
pallet 8 by the trough 36.
[0124] Moreover, the coil transport pallet 8 is characterized by a
coupling unit 40, by means of which it can be reliably coupled
temporarily to the coil transport vehicle 11.
[0125] This coupling unit 40 comprises, on the one hand, a coupling
peg parts 41 (numbered only exemplarily) which are arranged on the
inner frame 30 and extend in the direction of the longitudinal axis
20 of the coil transport pallet 8.
[0126] On the other hand, this coupling unit 40 has transverse
member parts 42 (numbered only exemplarily) which are formed by the
outer runner frames 25 and which extend transversely to the
longitudinal axis 20 of the coil transport pallet 8.
[0127] Here, the transverse member parts 42 of the inner frame 30
or of the coupling peg parts 41 are arranged axially spaced in such
a manner that a coupling space 43 forms in between, in particular
in the front and in the rear on the coil transport pallet 8.
[0128] In these coupling spaces 43, coupling elements 45 of a
coupling device 46 of the coil transport vehicle 11 can engage (see
FIGS. 3 and 4).
[0129] The coupling device 46 thus comprises the coupling elements
45 (numbered only exemplarily) which can cooperate with the
complementarily constructed coupling unit 40 on the respective coil
transport pallet 8.
[0130] Here, these coupling elements 45 interact with the coupling
peg parts 41 of the coil transport pallet 8 in such a manner that
the coil transport pallet 8 is coupled so that it cannot shift in
transverse direction relative to the longitudinal axis 20 on the
coil transport vehicle 11.
[0131] In addition, the coupling elements 45 interact, on the one
hand, with the inner frame 30 and, on the other hand, with the
transverse member parts 42 in such a manner that the coil transport
pallet 8 is coupled axially to the longitudinal axis 20 so that it
cannot shift on the coil transport vehicle 11.
[0132] However, in order to be able then to press a winding layer
49 (see FIGS. 5 to 8) of the wound coil 6 in the sense of the
invention through the coil transport pallet 8 onto said wound coil
6, the coil transport pallet 8 is equipped with a through-opening
50 for guiding a displaceable pressing element 51 of a pressing
mechanism 52 therethrough, for pressing at least one winding layer
49 and/or winding layer end 78 (see FIGS. 7 and 8) against the coil
6.
[0133] To that extent, the coil transport pallet 8 is designed with
a pressing element through-opening 50 which, in particular, is
adjusted to the size of the displaceable pressing element 51 in
such a manner that said pressing element can be guided without
problem from below through the coil transport pallet 8 up to the
wound coil 6.
[0134] Thus, the displaceable pressing element 51 is arranged on
the coil transport vehicle 11 in such a manner that it can be
displaced through the through-opening 50 in order to interact with
the wound coil 6.
[0135] To that extent, with the aid of the pressing mechanism 52,
the wound coil 6 can be deposited on the coil transport pallet 8 in
such a manner that the winding of the respective coil 6, which is
produced on the winding system 2, 3 or 4, can no longer spring open
later due only to interaction with the coil transport pallet 8 on
which the wound coil is deposited. As a result, it is
advantageously possible to dispense with additional tying machines
or the like for fixing the winding of the wound coil directly after
the winding system.
[0136] The through-opening 50 is arranged between two coupling
spaces 43 of the coupling unit 40, which are spaced from one
another by the through-opening 50, as well as between two runners
27 and 28 spaced from one another by the through-opening 50 and
forming the rolling and/or sliding surfaces 29.
[0137] Furthermore, the through-opening 50 is arranged beneath the
support device 35 and on the lower side 26 of the coil transport
pallet 8. As a result, the pressing mechanism 52 can advantageously
be arranged directly on the coil transport vehicle 11.
[0138] The shiftable pressing element 51 can be displaced without
problem up to the wound coil 6, if the through-opening 50 is
arranged in the trough 36 of the support device 35, since, by means
of the trough 36, the wound coil 6 can be placed particularly deep
in the coil transport pallet 8. Thereby, the wound coil 6 is placed
in the immediate vicinity of the displaceable pressing element
51.
[0139] The through-opening 50 extends with its longitudinal
orientation 53 in the direction of the longitudinal extent 21 of
the coil transport pallet 8 or of the coil accommodation space
38.
[0140] Furthermore, the longitudinal orientation 53 of the
through-opening 50 extends in the direction of the coil rotation
axis 23 of the wound coil 6 and, in addition, in the direction of
the rotation axis 54 of the pressing element 51, wherein the coil
rotation axis 23 and the rotation axis 54 extend axially parallel
to one another. Thereby, the pressing element 51, which is
displaceable through the through-opening 50, can interact through
the through-opening 50 in a constructively simple manner with the
wound coil 6.
[0141] The through-opening 50 moreover extends transversely to a
coil tying device 55 or coil tying opening 56 provided on the coil
transport pallet 8, with the help of which additionally the wound
coil 6 can be tied if this is desired.
[0142] In this embodiment example, the coil tying opening 56 is
between two bar elements 37 of the support device 35, which are
spaced from one another axially along the longitudinal axis 20.
[0143] As can be seen clearly in the representations of FIGS. 3 and
4, the respective pressing mechanism 52 can be arranged in this
embodiment example directly on the respective coil transport
vehicle 11 or coil discharge carriage 11, so that each coil
transport vehicle 11 can work independently with respect to the
pressing of the wound coil 6.
[0144] Here, the pressing mechanism 52 is formed in such a manner
that at least the displaceable pressing element 51, which is
implemented, for example, in the form of a roller element and, in
particular, in the form of a trough roller element 57, can be
displaced relative to the respective coil transport vehicle 11 and
brought in mechanical operational contact with the outer winding
layer 49 of the wound coil 6.
[0145] As already described, the displaceable pressing element 51
is mounted such a manner that it is linearly displaceable with
respect to the coil transport vehicle 11 on said coil transport
vehicle 11.
[0146] In order to be able to displace the displaceable pressing
element 51 in particular vertically with respect to the coil
transport pallet 8 or the coil/pallet unit 10, the pressing
mechanism 52 comprises a corresponding lifting device 60 which is
arranged in the center on the coil transport vehicle 11.
[0147] On its side 61 facing the coil transport pallet 8, the coil
transport vehicle 11 comprises a pallet moving device 65, wherein
the present pallet accommodation 11A is an upper component of the
pallet moving device 65 of the coil transport vehicle 11 on which
the coil transport pallet 8 is deposited.
[0148] In this embodiment example, the pallet accommodation 11A is
formed as frame part 62 which surrounds in particular the
displaceable pressing element 51 of the pressing mechanism 52
arranged on the coil transport vehicle 11.
[0149] By means of the pallet moving device 65 thus formed, the
coil transport pallet 8 can be lifted independently of the
displaceable pressing element 51 to a position under the wound coil
6, so that the coil 6 which then interacts with the coil transport
pallet 8 can optionally also be pulled off the winding mandrel 7 by
means of the coil transport vehicle 11 and discharged as
coil/pallet unit 10 from the winding system 2, 3 or 4.
[0150] The pallet moving device 65 for this purpose can be moved
vertically by means of a lifting device 66.
[0151] For the rest, the coil transport vehicle 11 also comprises
four wheel elements 67 (numbered only exemplarily), by means of
which it can be moved in a mobile manner along a discharge section
68.
[0152] According to the representation of FIG. 3, the coil
transport vehicle 11 is shown in an extended state with respect to
the lifting device 66, wherein the coil transport pallet 8 is
coupled to the pallet accommodation 11A of the coil transport
vehicle 11. In the process, the pressing element 51 is displaced
from below far into the trough 36 and can thus come in contact
early on with the outer winding layer 49 or with the winding layer
end area 78 (see FIGS. 7 and 8) and be pressed against the wound
coil 6.
[0153] According to the representation of FIG. 4, the coil
transport vehicle 11 is shown alternatively also without coil
transport pallet 8 and in a retracted state with respect to the
lifting device 66.
[0154] Based on the discharge device 5 shown in greater in detail
in a front view in FIGS. 5 to 8, an exemplary method sequence is
shown and explained, which can be implemented with the special coil
transport pallet 8 or with the coil transport vehicle 11.
[0155] The wound coil 6 is here still held by the winding mandrel 7
on one of the winding systems 2, 3 or 4.
[0156] The discharge device 5 comprises, in particular, the coil
transport vehicle 11 which can be placed beneath the winding
mandrel 7 or the wound coil 6 and which is parked with the coil
transport pallet 8 already under the wound coil 6 while the coil 6
is still in the process of being completely wound.
[0157] To the extent that the pressing mechanism 52 is provided by
means of the coil transport vehicle 11 on the winding system 2, 3
or 4.
[0158] As shown in the representation according to FIG. 5, the
steel strip 6A is supplied in a known manner from the top left to
the winding mandrel 7 by means of a feed device 70.
[0159] Concentrically around the winding mandrel 7, three
deflection and pressing devices 71, 72 and 73 are arranged, by
means of which the winding process can be facilitated in a known
way. The three deflection and pressing devices 71, 72 and 73 can
thus be designed as so-called deflection shells.
[0160] Each of the deflection devices 71, 72, 73 comprises a
delivery mechanism 74 (numbered only exemplarily) by means of
which, if needed, the deflection and pressing rollers 75 (also
numbered only exemplarily) can be delivered to the coil 6 to be
wound.
[0161] In particular, if the steel strip 6A is cut, the winding
layers 49 of the wound coil 6 can be held together by means of
these deflection and pressing rollers 75, so that the wound coil 6
is secured against unwanted springing open.
[0162] According to the representation of FIG. 5, the displaceable
pressing element 51 of the pressing mechanism 52 of the coil
transport vehicle 11 is still retracted downward into the coil
transport vehicle 11. The same applies with regard to the pallet
moving device 65.
[0163] According to the representation of FIG. 6, the displaceable
pressing element 51 is already displaced through the coil transport
pallet 8 in vertical direction 76 vertically upward in the
direction of the wound coil 6, in particular, to the point that it
presses the outer winding layer 49 against the wound coil 6 (in the
broken-line representation of the displaceable pressing element 51,
it is shown still in the lower position).
[0164] The steel strip 6A has already been cut by a cutting device
(not shown) or it is cut now, and, in particular, the outer winding
layer 49 of the completely wound coil 6 is now pressed in
particular by the displaceable pressing element 51 against the
completely wound coil 6, so that it is ensured that the wound coil
6 cannot spring open accidentally.
[0165] The wound coil 6 is rotated further in accordance with
rotation direction 77 until the winding layer end 78 is located
approximately in the 17:00 o'clock position 79 (see, in particular,
FIGS. 7 and 8).
[0166] If the winding layers 49 of the wound coil 6 are
satisfactorily secured by the displaceable pressing element 51 of
the pressing mechanism 52 of the coil transport vehicle 11, the
right lower deflection and pressing device 72 is moved by a
swiveling movement 80 from the area of action 81 of the coil
transport vehicle 11 so that then, by means of the hydraulically
operating lifting device 66, the coil transport pallet 8 supported
by the pallet moving device 65 can be moved from below against the
wound coil 6 in such a manner that the wound coil 6 is deposited on
the coil transport pallet 8 as shown according to the
representation of FIG. 7 (the broken-line representation of the
coil transport pallet 8 shows this coil transport pallet still in
the lower position).
[0167] If the wound coil 6 is now supported operationally reliably
by the support device 35 of the coil transport pallet 8, the
displaceable pressing element 51 can again be displaced in the
direction of the coil transport vehicle 11 vertically downward, as
illustrated according to the representation of FIG. 8.
[0168] The wound coil 6 is now deposited on the wound transport
pallet 8 in such a manner that a springing open of the wound coil 6
is impossible due to the contact with the coil transport pallet 8
is impossible.
[0169] The load of the wound coil 6 is taken up completely by the
coil transport pallet 8, so that, in the winding system 2, 3 or 4
and with the aid of the lifting device for the pallet 66, the
respective coil/pallet unit 10 is produced.
[0170] The wound coil 6, together with or using the coil transport
pallet 8, can thus be pulled from the winding mandrel 7 with the
aid of the coil transport vehicle 11 and discharged from the
winding system 2, 3 or 4. If the wound coil 6 is free of the
winding mandrel 7, the lifting device 66 is retracted again, and
the coil transport pallet 8 or the coil/pallet unit 10 is lowered.
Subsequently, the wound coil 6 is transferred to the stationary
ground conveyor device 15, as already explained at the start.
[0171] The coil/pallet unit 10 is rotated, during subsequent
transport, on the rotating table unit 17 of the stationary ground
conveyor device 15 by 90.degree. about the vertical axis 81. To
that extent, the coil/pallet unit 10 undergoes a change in
direction on the rotating table unit 17 and accordingly can be
transported further to a destination site, without the wound coil
having to be taken off the coil transport pallet 8 once
associated.
[0172] Subsequently, with the aid of the rotation table unit 17 and
the coil transport vehicle 11, a new coil transport pallet 8 is
moved to a position under the winding mandrel 7 of the respective
winding system 2, 3 or 4, so that, with the assistance of the
pressing mechanism 20, a new coil/pallet unit 10 can be produced
there.
[0173] Here, it is pointed out explicitly that the features of the
solutions provided above and described in the claims and/or figures
can optionally also be combined, so as to be able accordingly to
cumulatively implement or achieve the explained features, effects
and advantages.
[0174] It should be understood that the above explained embodiment
example is only a first design of the coil transport pallet or of
the coil transport vehicle. To that extent, the design of the
invention is not limited to this embodiment example.
[0175] All the features disclosed in the application documents are
claimed as essential to the invention, to the extent that they are
novel separately or in combination with respect to the prior
art.
